Trait measurements of the phytoplankton species Chaetoceros affinis and Emiliania huxleyi

Trait measurements for growth, nutrient uptake, and cell volume for nine genotypes each of the phytoplankton species Chaetoceros affinis and Emiliania huxleyi individually during 4 days of cultivation at seven nitrate levels. Nitrate levels for genotypes of C. affinis were 2.5, 5, 7.5, 12.5, 20, 30, and 45 μmol L−1 with 2 μmol L−1 phosphate and 2.5, 5, 7.5, 10, 15, 20, and 25 μmol L−1 with 1.5 μmol L−1 phosphate for genotypes of E. huxleyi.
